Answer 1

Answer:
`190ft`

Explanation:

Side a= 110ft

Side b= ?

Height= 75ft

Area=
`11,250ft^2`

`A=(a+b)/(2)h`

Solve for b. Let's begin by multiplying by 2 to get rid of the denominator.

`2A=(a+b)h`

Divide by h

`(2A)/(h)=a+b`

Subtract a

`(2A)/(h)-a=b`

Now plug in your values.

`b=(2A)/(h)-a`

`b=(2(11,250ft^2))/(75ft)- 110ft`

`b=(22500ft^2)/(75ft)- 110ft`

`b=300ft- 110ft`

`b=190ft`
